Description

Multi-animal Monitoring & Gating

Multi-animal monitoring and gating systems have been designed to meet the physiological monitoring and gating needs for anesthetized mice, rats and larger animals in the MR, PET, CT, SPECT, Optical and laboratory environments. Systems can be configured to accommodate up to 20 animals.  Each system consists of one or more ECG, respiration and temperature (ERT) data acquisition and processing modules located near the animals and a PC Interface (PCI) module connected to a PC located near the operator console. The PC displays multiple waveforms, measured values, trends and gating pulses for all the animals. The data acquisition modules are controlled by menu driven software from the PC. Systems can be configured to accommodate multiple animals in multiple imaging environments.

ECG waveforms are measured for each animal using two or three leads with sub-dermal needle electrodes, gold disk surface electrodes or radio translucent pads.  Each ECG waveform is processed to detect the R-wave, generate an ECG gate and to determine the heart rate. Temperature is measured using small thermister temperature probes.  The temperature probe can be located in the rectum or on the animal’s skin. Respiration is obtained from small pneumatic pillow sensors placed next to the abdomen of each animal.  The waveforms are automatically processed to detect inspiration, expiration and respiration rate. Auxiliary gate input channels allow the user to synchronize the animal’s physiological measurements with data from the imaging system which in turn allows retrospectively gated images. Gating algorithm, which is user configured, allows gates to be generated for each animal from ECG, respiration or ECG and respiration..  The user can control the start, stop and width of each animal’s gate. Power for the ERT module is supplied from a battery.  The PC Interface Module is powered from an external 12 VDC power supply operating from 100-230 VAC, 50-60 Hz. Compatible with imaging systems for all manufactures.
